Who are the best fighters of the last 10 years not to have won a world title?

Here's a few

.David Tua
.Zahir Raheem
.Rocky Juarez

I don't know about Juarez, isn't he like 0-8 in title fights? That first Barrera fight was hella entertaining and competitive, but I think that had more to do with Marco fading and fighting the wrong fight.
